VINEYARD OR ORCHARD CULTIVA'T'OR.

SPECIFICATION forming part of Letters Patent No. 735,986, dated August 11, 1903.

Application filed March 25, 1903.

T0 all whom t may concern,.-

Be it known that I, IRA B. KILGORE, a citizen of the United States, residing` at Concord, county of Contra Costa, State of California, have invented an Improvement in Vineyard and Orchard Cultivators; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus which is especially designed for cultivating the soil where vines or trees are growing' in rows; but it is also applicable to other forms of cultivation.

It consists of a series of curved cultivatorteeth fixed to' independent swiveling frames, which are also turnable forward and back, and a main frame upon which these segmen- Y tal frames are carried in such a manner that they may be reversed to stand upon either one side or the other.

It also comprises means for raising and lowering the supplemental frame, so as to vary the angle of the teeth in the direction of the line of travel.

My invention also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which-e Figure l is a perspective View of my invention. Fig. 2 is a perspective view of one tooth.

It is the object of my invention to provide a cultivator which can be driven between rows of growing vines, trees, or like objects, so as to thoroughly cultivate the soil between the rows, and to so construct the device that the angle of the cultivating-teeth to the line of travel may be changed, so as to throw the soil to or from the rows between which the apparatus is traveling, and also to so change the forward and backward tilt of the teeth that they may be more or less upright with rclation to the line of travel.

As shown in the accompanying drawings, A is the pole to which the team may be attached, asl will hereinafter indicate.

2 represents rectangular U-shaped irons bolted to the p'ole, with the bottom part of the U extending parallel with and just below the pole, and this part is perforated with holes, as

be regulated by means of a pin passing.

through the holes in the segment or by other well-known equivalent means.

7 isa clevis to which the team is attached to haul the machine, this being located well towardthe rear of the pole, so as to bring the draft close to the cultivator portion.

. S is a bent or cranked axle the central portion of which is attached beneath the rear end of the beam and the crank portions bend downward on each side, and the ends are again bent outwardly parallel with the central portion, forming journals which are iitted into boxes 9, as shown. These boxes are firmly braced to the pole A in front of the part 2 by brace-rods 10, the front ends of which are bolted to the pole and the rear ends connected with the boxes, and these, in conjunction with the bent arm 8,' form atriangular support forthe boxes 9. From the extensions of the rear ends of these boxes other braces 11 extend upwardly and are bolted to the rear portion of the seat-bar 4.

12 represents beams adapted to carry the harrow 'or cultivator teeth 13. These teeth are made of steel preferably about three by iive-eights inches, and the upper ends are bent at an angle, aspshown at 14, so as to be bolted or riveted upon the under side of the flat steel beams 12. The lower ends of the cultivatorlteeth are curved slightly to one side, and the toothed bars 12 are pivoted to the rear extensions of the j ournal-boxes 9 by vertical bolts, as shown at 15. This allows the tooth-bars 12 to be swiveled around these vertical bolts, so as to change the angle of the cultivator-teeth with reference to the line of travel. Thus by turning the beams in either direction the teeth will be made to throw the dirt more or less out of the line of travel of the machine and to or from the rows between which it is traveling.

change the throw of the dirt, it is only neces- IOO If it is desired to p sary to remove the bolts 15, taking off the tooth-bars 12 and reversing themthat is, placing the one at the right upon the left and the one at the left upon the right-thus changing the throw of the dirt by reason of the curvature of the lower parts of the teeth.

In order to swivel the tooth-bars 12 about their vertical pivots 15 1 have shown rods 1G, the rear ends of which are attached to the inner adjacent ends of the tooth-bars 12, and the front ends are connected with the bottoms of the U-shaped bars 2 by pins passing through the holes 3, previously described. By adjusting these rods 1G forward or back in the holes 3 it will be seen that the angle of the bars 12 with relation to the line of travel will be changed. As shown in the present case, the connection of the rod 1G with the bars 12 is made by means of foot-rests 17, which are adapted to be bolted to the adjacent ends of the bars 12. Holes are inade in the outer' and the inner ends of these bars, so that when the bars are reversed, as previously described, the foot-rests can be changed so as to always be located at the inner ends of the bars 12. These foot-rests also serve in a manner to assist in steering the harrow to or from the row. Thus if it be found that the harrow is running too close to the row on one side the driver may bear his weight upon the foot-rest upon that side, thus sinking the teeth of that section more deeply into the ground and correspondingly forcing the barrow away from the rows. By reason of the curvature of the teeth from the top to bottom the line of draft and the center of the bars 12 will differ somewhat, and the pivotbolts 15, by which the bars 12 are attached to the boxes 9, are placed as near the center of the line of draft as possible and not necessarily in the center of construction from end to end of the bars.

If it be found desirable to change the angle of the teeth 13, it is eifected by reason of lowering the seat-beam 4 upon the segment 6 and by means of the brace-rods 11, which extend from the seat-beam to an extension behind the box 9, the raising of the seat-beam will tilt the bars 12 about the journals at the end of the crank-arm 8 and thus project the teeth backwardly and into a more nearly horizontal position, while by depressing the seat-bar 4 the teeth will be set up into a more vertical position.

Thus constructed the device has proved very superior in practice for the class of work for which it is designed.

Having thus described my invention', what I claim, and desire to secure by Letters Paten t, is-

1. A cultivator comprising a pair of bars turnable upon vertical pivots and having curved teeth projecting downwardly; a pole 5 a yoke fixed to the pole and having its lower ends hingedly attached to the bars at one side of the pivots; a hinged seat-beam and rods secured to the rear portion of the beam and vease@ diverging downwardly and attached to the bars at the opposite side of said pivots.

2. A eultivator consisting of vertically and centrally pivoted tooth-bars having cultivator-teeth fixed to and extending downwardly and rearwardly therefrom, a draft-pole, a bent yoke attached and extending downwardly from the rear of the pole, journalboxes in which the ends of the yoke are litted, said boxes having rearward extensions to which the tooth-bars are pivoted, braces connecting the boxes with the pole, and rods adj ust-ably connecting the inner ends of the tooth-bars with the pole whereby said bars may be turned to varying angles with the line of travel of the machine.
